By using megger for underground cables we can find the faults in
it. by using megger for underground cables we can find fault. when
megger is connected between the conductors of underground cables ,
when megger shows the zero resistance then there is a short circuit
fault in the cables.
when megger shows infinite then there is open circuit fault in
the underground cables.
Devices used for the detection of fault
megger
conductor
meters
process for detecting faults in underground cables
Cable thumping
TIme domain reflectometer
high voltage radar methods
Easy method to find fault is using megger
